Broken Spark Plug - Need help fast

By the way, there are two important processes that should be considered with
aluminum heads and steel spark plug threads.
1. the different rate and extent of thermal expansion
:heating and cooling might break the corrosion bond

2. electrolysis between dissimilar metals causes corrosion between the
surfaces.
: there are compounds that should be applied to the plug threads to reduce
the effects of electrolysis.
